KABUL, April 7 (Xinhua) -- At least six militants of Islamic State (IS) terrorist group have been killed following airstrikes conducted by the U.S. and NATO-led coalition forces in two Afghan provinces, authorities said Saturday.

In one attack, a local IS leader named Qari Hekmat along with one of his subordinates was killed after a coalition plane struck a location in Sar Dara area, Darzab district of northern Jawzjan province Friday noon, Hanif Rezai, spokesman of Afghan army Corps 209 Shaheen based in the region, told Xinhua.

Hekmat was leading IS militants in Jawzjan and the group has appointed Habib-ul-Rahman as the temporary leader of IS in the province.

In eastern Nangarhar province, four IS militants were killed after an unmanned plane of the coalition bombed the Dara Takhta area of restive Achin district.

The two provinces have been the scene of heavy clashes between security forces and IS militants.

The group, which emerged in early 2015 in Afghanistan, has yet to make comments on the reports.
